Thanks, I got it to work by switching to Maximum. Not sure Comp in Front doesn’t work. What does Maximum (and Minimum for that matter) actually mean?
> One problem you may run into is that the echo effect won’t be fully displayed until you are several seconds into the animation since it’s referencing an earlier point in the timeline to create the copies, so you may need to create an animation where the moon starts out of frame to account for this.
I am seeing this, will do that…
